What are the apparent advantages and potential disadvantages of focusing your self-development on achieving excellence in a specific technical or professional specialty?

Being experts has many advantages and disadvantages for your professional career. Whether in the specific technical or professional specialty, an expert is one who has mastered a branch or an area with specificity and skill. This professional stands out for having a number of striking features. One is the focus on innovation; He is keen to create products and services that appeal to the target audience.

One of the disadvantages of being an expert is that companies need to cut back on expenses, so they are looking for people who know how to do so (not just one, like the expert) so they don't have to hire one just to solve that. The second disadvantage is that the specialty that the professional has chosen may be just a fad that, when passed, will leave the professional displaced professionally.

As an advantage, specialists get higher pay especially when they master difficult areas where few professionals work. Another advantage is that these professionals have advantages in selection processes because of their advanced level of academic education.
